Verdict

The call

The clearest difference is in-app purchases: Function Health at none against VetlyHealth's 9. Function Health also leads on ads (none vs shown) and ratings volume (25K vs 2). VetlyHealth's advantage is device support (3 vs 1) and iOS requirement (13.0 vs 16.4). On price and rating there is nothing between them.
